Upgrade your workshop tool kit with these ultra-compact stubby driver handles designed for standard 1/4" hex bits. Built for tight spaces where a full-size driver can’t reach, each handle features hollow internal storage to stash your extra bits on the go.

  • Two Size Variants: Modeled specifically for standard 1" bits and longer 2" bits.

  • Modular Ergonomics: Choose between smooth straight grips or finger-grooved contours, paired with your choice of a flat cap or rounded-over cap for comfortable palm pressure.

  • Magnetic Bit Retention: Includes an internal socket for a 6mm x 3mm neodymium magnet. Because the magnet channel is slightly smaller than the 1/4" hex drive profile, it can be press-fit from either direction during assembly to keep your bits locked in place.

  • Snug Friction-Fit Caps: The caps push-fit tight to keep stored bits secure inside the handle without rattling loose.

🛠 Maker Note: This design is fresh off the CAD setup! If you print a set, please drop a comment, upload a make, or share your feedback on the tolerance and fit so I can fine-tune future updates.

 

Dimensions

1” Bit Version:

  • OD: 1.155”

  • Length: 1.5”

  • Bit Inset Length: 0.3”

  • Storage Dia: 0.65”

  •

Print Settings

  • Material: PETG or ABS/ASA (Recommended for workshop durability, drop resistance, and torque strength).

  • Layer Height: 0.12mm to 0.20mm (Lower layer heights yield cleaner friction-fit tolerances on caps).

  • Wall Loops / Perimeters: 4+ walls (Crucial for functional tools—extra walls handle high twisting torque far better than extra infill).

  • Infill: 20% or higher (Gyroid or Grid pattern for balanced structural integrity).
